T o all Awhom t may concern Be it known that l, CLEMENT V. vWirral.-

LoN, a citizen of the United States, residing g lcharacter is to provide a cap or lid of a very simple construction and which is very easily attached to or detached from the body to which the lid or cap is applied.

A further object is to provide a means for locking a lid, cap or stopper in place against removal from a body to which it is applied, includinga bolt or screw and a member which, as the bolt nr screw is rotated, has an increasingly weuging engagement with the body.

A further object is to provide a lid having means carried entirely on the lid whereby it may be engaged with and locked upon a body.

A still further object is to provide a lid or stopper adapted to be applied to annular or other bodies to closethe same, thev lid being provided with an integral lug having a beveled face and with a locking bolt passing through the lid and having a nut which, when the bolt is turned in one direction is forced into wedging engagement with the inclined face of tue wall of the body to thereby lock the lid or stopper upon the body.

Figure l is a diametrical section through a tubular body and a cap or lid for the same constructed in accordance with niy invention; and

Fig; il is a plan view of the construction4 a beveled face 12 and preferably the'l lugat its end opposite the beveled tace and at its junction with the inner face of the cap 10 is termed with a notch 13. The lug l1 does not extend entirely across the under tace of the lid, but the lid is formed with a bolt hole through which a bolt 1lextends. rlhe head l5 otthis bolt'is preferably manysidedand is usually, though not necessarily,

contained in a countcrsunk recess 1 6 in the outer face oi' the cap 10. rlhe bolt let at its lower end is screw-threaded as usual and carries a nut 17 and is upset at lela to prevent therenioval of the nut- 17.

ln the use of this invention, the cap is applied over the body 18 in the manner illustrated with the lug 11 inserted within the body and the nut 17 at the lower end or" the bolt. The passage through the lid for the bolt expands downward so that the bolt has a slight play. Now the lid is inserted and then the bolt is turned by means of the many-sided head. The nut is held 'from rotation between the side wall of the body and the extreme lower corner of the lug and, as a consequence, the nut cannot turn though it can shift. By now rotatingr the head of the bolt, the nut is drawn upward into wedgingengagement between the inclined face of the lug` and the wall of the casing or body to which the lid is applied. By rotating the bolt in the opposite direction, the nut 17 will be gradually worked down until it is released from its wedging engagement so that the cap may be removed.

This lid, cap or stopper, though primarily designed for repair purposes, can also be used for closing' a pipe, box, or other receptacle in the lirst instance. lt is particularly designed and peculiarly adapted for use as a cover or lid for water and gas meter boxes and for the shut-off boxes of water, gas and sewer pipes. The same principle, however, can be used for the lids or covers of inanholes or for any box, pipe, or casing. size of the lid will, of course, depend upon the size of the box and the thickness of the lid and the size of the locking devices will also, of course, depend upon the size of the body to which it was to be applied and the strain which would be liable to come upon this body. The notch 13 is provided in the lug 11 -lor the purpose ot giving room for the slight `flange or lin caused on the inside ot' the pipes by the cutting of the pipes in repair Work. This notchl fits over this The iin it the is present5 and gives the lug` a irin Contact over its end surface with the pipe or body in enses where old pipe has been eut and this device is used thereon, while at the same time this noteh will not aiieet the Contact of the lug where the new pipe or easing is used. wish it particularly understood that do not lirnit iny de- 'vice to its use es a means 'for Closing pipes or the boxes or easings of water or gas nieter boxes, etal, es the principle ot the device may be used in a large nu'niber of Circumstances to secure the closing of e body and the locking of the Closure thereto.

I elaiinz i, A self locking lid or stopper comprising a Cap having at lug extending from its inside aee and disposed dianietrieally to the cap, one end of the lug being inclined, a bolt passing down 'ard through the Cap opposite seid inclined face, and a nut engaging said bolt and engageable with the inclined tace of the lng.

Si. self locking lid including a cap having n downwardiy extending diametrieally disposed lug, one end of the lug being beveled downwardly and Centrally, a bolt passing through the nap opposite said beveled end, and a nut engaging the screwthreads o't' the bolt and engageable with the beveled faee of the lug7 the opposite end of the lug adjacent the inner face t' the Cep being formed with a notch.

3. The Combination with a body having en upstanding wail, oit a cap for closing' pas! ieee-,51e

sage through the body and having ev lug extending downward into the body. one end of the llug being adapted to tit against the inside tace ot' the body, the opposite end of the lug being beveled upward and outward, a bolt loosely disposed through the cap and having a many-sided head whereby it may be rotated. and a nut engaging the screwtlirends ot the bolt, the nut bearing against the inside tace olf the body and against the beveled fave of the lug when the nut is turned upward on the bolt.

l. T he combination with a body having en upstanding wiall, of a Cap having a projecting lug and ineans mounted on the cap adapted to be shifted into wedging engagement between the wall and the lug to prevent the removal of the eap.

The (,onibination with a body having an upstanding wall, ot ay Cap for closing the body, and means for locking the eap to the body comprising a lug depending from the body havingl an upwardly and outwardly beveled face, a nut engage-able between the beveled 'face ot' the lug and the wall of the body. and means on the cap whereby the nut niay be forced into said wedging engageinent to thereby look the Gap to the body.

in testimony whereof l hereunto alliX my signature in the presence of two witnesses.
